System and method for editing materializations of a data store

A computer-implemented method comprising:

• receiving edit revisions to a data structure;
• storing the edit revisions to the data structure in a shared data set;
• generating, from a first set of pointers, a first baseline of the data structure, wherein each pointer in the first set of pointers points to an edit revision in a first set of edit revisions stored in the shared data set, and wherein the first baseline defines a first materialization of the data structure;
• applying a first change command and a second change command to the first set of edit revisions to determine a second set of edit revisions to the data structure;
• generating, from a second set of pointers, a second baseline of the data structure, wherein each pointer in the second set of pointers points to an edit revision in the second set of edit revisions, and wherein the second baseline defines a second materialization of the data structure;
• determining an inverse of the first change command;
• applying the inverse of the first change command to the second set of edit revisions to determine a third set of edit revisions to the data structure;
• generating, from a third set of pointers, a third baseline of the data structure, wherein each pointer in the third set of pointers points to an edit revision in the third set of edit revisions, and wherein the third baseline defines a third materialization of the data structure;
• generating, from the third baseline of the data structure, user interface information comprising the third materialization of the data structure;
• and
• providing the user interface information to a computing device.

A non-transitory, computer-readable medium having stored thereon computer-executable software instructions configured to cause a processor of a computing device to perform operations comprising:

• receiving edit revisions to a data structure;
• storing the edit revisions to the data structure in a shared data set;
• generating a first pointer block comprising a first set of pointers, wherein each pointer of the first set of pointers points to an edit revision in a first set of the edit revisions stored in the shared data set;
• generating, from the first set of pointers, a first baseline of the data structure, wherein the first baseline defines a first materialization of the data structure;
• applying a first change command and a second change command to the first set of the edit revisions stored in the shared data set to determine a second set of the edit revisions to the data structure;
• generating, from the second set of the edit revisions, a second pointer block comprising a second set of pointers, wherein each pointer in the second set of pointers points to an edit revision in the second set of the edit revisions;
• generating, from the second set of pointers, a second baseline of the data structure, wherein the second baseline defines a second materialization of the data structure;
• determining an inverse of the first change command;
• applying the inverse of the first change command to the second set of the edit revisions to determine a third set of the edit revisions to the data structure;
• generating, from the third set of the edit revisions, a third pointer block comprising a third set of pointers, wherein each pointer of the third set of pointers points to an edit revision in the third set of the edit revisions;
• generating, from the third set of the edit revisions, a third baseline of the data structure, wherein the third baseline defines a third materialization of the data structure;
• generating, from the third baseline of the data structure, user interface information comprising the third materialization of the data structure;
• and
• providing the user interface information to a computing device.
